English abstract:
Determination of the volume of weights is necessary for the correction of air buoyancy, and thus is an essential capability for today´s metrology institutes. The Austrian Federal Office of Metrology and Surveying (BEV) and the Vienna University of Technology, at the request of and in cooperation with Sartorius AG in Goettingen, have developed a fully automatic load alternator for weighing below the mass comparator, for use in volume determination of E1 weights and plummets using 1-kg mass comparators. Thus, the hydrostatic weighing principle can be applied for serial volume on masses from 1 g to 1 kg through direct comparison with a single volume reference (e.g., a silicon sphere). This is implemented with a newly developed, fully automatic insertion mechanism for both completely submersed weights and substitution weights. This system is used at the BEV for volume measurements in connection with the determination of mass, as well as in other metrology institutes and accredited calibration laboratories.

Um die, zur Luftauftriebskorrektur erforderliche Bestimmung des Volumen von Gewichtstücken durchführen zu können wurde in Zusammenarbeit mit dem BEV und der Firma Sartorius ein vollautomatisches Gerät zur Eichung von bis zu neun Gewichtsstücken entwickelt und realisiert.
